<p><b>Syntax:</b> <i>rtsig_overflow_*</i>
</p><p><b>Default:</b> <i> </i>
</p><p>These directives specifies how to handle rtsig queue overflows. When overflow occurred nginx flushes rtsig queue, then it handles events switching between poll() and rtsig. poll() handles consecutively all unhandled events, while rtsig periodicaly drains queue to prevent a new overflow. When overflow is handled completely, nginx switches to rtsig method again.
</p><p>The rtsig_overflow_events specifies the number of events to be passed via poll(). The default is 16.
</p><p>The rtsig_overflow_test specifies after which number of events handled by poll() nginx will drains rtsig queue. The default is 32.
</p><p>The rtsig_overflow_threshold works in Linux 2.4.x only. Before to drain rtsig queue nginx looks in a kernel how the queue is filled up
</p><p>The default is 1/10. "rtsig_overflow_threshold 3" means 1/3.
